IMPROVEMENT IN CHURNlNG-MACHINES.

Specification forming part of Letters Patent No. 220,474, dated October 14, 1879; application filed June 14, 1879.

To all whom it may concern:

Be it known that I, J Aims THOMAS HAILE,

of Whitesborough, in the county of Grayson ings, making a part of this specification, and

to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a front view of my improved machine, and Fig. 2 is a vertical section thereof.

This invention has relation to improvements in mechanisms for operating churns; and the nature of the invention consists in the construction and novel arrangement of the devices used, as will be hereinafter more fully set forth.

- In the accompanying drawings, the letter A designates an upright stand, composed of two standards, a, fitting each into a base, a, and braced at top by a cross-beam, b. B designates a strong open-work metallic frame, havin g curved outwardly-bent legs 0, secured both to beam b and standards a by means of horizo'ntal bolts 6, and provided with three or more metallic angular holding-plates, d, that straddle the beam 1), and are secured thereto by means of the vertical bolts 6. findicates. a boss, extending outward. from frame B, and afiording bearings to the spindle g of a master-wheel, G. This spindle is carried through the frame, and is provided on its rear end with a crank-wheel, D, having a wrist, h,'that is adjustable to or from' the center of the wheel in a radial slot, 8, formed therein, for a purpose hereinafter set forth.

E represents parallel ways, havm g laterallyextended lugs l at top and bottom, by means of which and suitable bolts Z they are readily secured to the lateral edges of the frame. The

lugs Z are considerably thickened, the object being to form a space, m, between the frame and ways, in which the crank-wheel revolves without interference with either.

J indicates a sash, consisting of two end bars, it, connected by a horizontal cross-piece, at, having a horizontal slot, 8'. This sash in its general outline resembles the letter H, and the branches of the end bars, n, extend equally above and below the cross-piece n, and fit neatly, after the manner of the side rails of a sash, in the ways E. The wrist h extends through slot 8, and is provided with an antifriction roller, 1", fitting in said slot and rotating on the said wrist. The piece a has near its lower edge a horizontal eye, 0, through which the dash-rod L extends, being adjusted therein, according to the quantity of cream in the vessel, by means of a set-screw, 19.

By adjusting the wrist h nearer to or farther from the center of the wheel D, the length of the stroke of the dash-rod is lessened or in creased at pleasure.

It will be seen by an examination of Fig. 2 that the frame, sash, ways, and dash-rod are one side of the cross-bar, and the master-wheel on the other side thereof, thus creating a balance that effectually maintains the apparatus upright.

What I claim as new, and desire to secure by Letters Patent, is-- The combination, with the base A, consisting of the uprights a and cross-piece b, of the frame B, having curved bent legs a, secured thereto, and angleplates d, the ways E, the sash J, arranged in said ways and provided with a horizontal slot, 8, the master-wheel O, rotating on said frame, the crank-wheel D, having wrist-pin h, provided with anti-friction roller 1", the eye 0 on said sash, the setscrew 19, and dash-rod L, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

J. T. HAILE.
